Part 8/15:
- Possible Craters and Impact Sites: While no definitive crater from this period is currently identified, some geological features, such as submerged holes in Hudson Bay exhibiting impact rim-like structures, warrant further investigation.
The Climatic and Biological Aftermath
The impact likely caused immense environmental disturbances:
- Sudden Climate Changes: The Younger Dryas was characterized by rapid cooling, extinction of megafauna, and significant shifts in flora and fauna. The hypothesis links these to impact-induced wildfires, atmospheric dust, and abrupt meltwater discharges resulting from impacts on ice sheets.
